[0002] In the non-ferrous metal smelting and processing industry, the recycling and utilization of waste residues has become a crucial component of energy conservation, emission reduction, and the development of a circular economy. Crushing waste residues is a key prerequisite for subsequent sorting and purification processes. However, current non-ferrous metal waste residue crushing equipment still faces numerous technical challenges in practical applications, making it difficult to meet the demands for efficient and precise crushing.

[0003] Existing crushing devices generally have the problem of insufficient feed control capabilities. The feed inlets of traditional equipment are mostly fixed structures. During the unloading process, the crushing chamber is prone to uneven load due to material accumulation, which not only affects the crushing efficiency, but may also cause damage to the motor due to instantaneous overload.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Example 1: Please refer to Figure 1 、 Figure 2 and Figure 3 A non-ferrous metal waste slag crushing device includes a processing tank body 1, a motor 2 is fixedly connected to the side of the processing tank body 1, a drive shaft 3 is fixedly connected to the rotor of the motor 2, the drive shaft 3 passes through the processing tank body 1 and is transmission-connected to a cone crushing assembly 4, the cone crushing assembly 4 includes a longitudinal crushing shaft 5 rotatably connected to the processing tank body 1, a crushing unit 6 is arranged on the outside of the longitudinal crushing shaft 5, and a feed control unit 7 for controlling the discharge of materials is arranged on the top of the longitudinal crushing shaft 5.

[0032] When in use, non-ferrous metal waste slag is placed from the top of the equipment, and the motor 2 is turned on at the same time. The rotation of the motor 2 drives the drive shaft 3 to rotate, and then drives the longitudinal crushing shaft 5 to rotate. The longitudinal crushing shaft 5 drives the cone crushing assembly 4 to crush. At the same time, the longitudinal crushing shaft 5 can control the feed control unit 7 by controlling the direction and speed to achieve control of the feed amount.

[0033] See also Figure 4 A support bracket 8 is fixedly connected to the bottom of the processing tank body 1. An annular guide plate 9 is provided between the feed control unit 7 and the crushing unit 6. The annular guide plate 9 is fixedly connected to the processing tank body 1. When the waste slag passes through the feed control unit 7 and enters the cone crushing assembly 4 for crushing, it is guided by the annular guide plate 9 to ensure that the waste slag can enter the crushing position and avoid falling from the side.

[0034] See also Figure 3 、 Figure 4 and Figure 7 The crushing unit 6 includes a positioning ball 10 fixedly connected to the outside of the longitudinal crushing shaft 5, and a ball sleeve 11 is rotatably connected to the outside of the positioning ball 10. A crushing cone 12 is connected to the bottom of the ball sleeve 11. The crushing cone 12 is conical. The crushing cone 12 cooperates with the fixed cone 13 on the side of the processing tank body 1 to crush the waste slag. An eccentric driving column 14 is fixedly connected to the outside of the longitudinal crushing shaft 5, and a transmission groove that cooperates with the eccentric driving column 14 is opened at the bottom of the crushing cone 12.

[0035] The rotation of the longitudinal crushing shaft 5 simultaneously drives the eccentric drive column 14 to rotate. During the rotation of the eccentric drive column 14, the crushing cone 12 moves, so that the crushing cone 12 cooperates with the fixed cone 13 to achieve crushing. At the same time, the longitudinal crushing shaft 5 also synchronously drives the feed control unit 7 to achieve feed control.

[0036] The fixed cone 13 includes an annular cone 15, and an adjusting block 16 is fixedly connected to the outside of the annular cone 15. An adjusting groove 17 is opened on the side wall of the processing tank body 1. The adjusting block 16 passes through the adjusting groove 17 and is slidably connected to the processing tank body 1. A positioning block 18 is fixedly connected to the side wall of the processing tank body 1. An adjusting bolt 19 is rotatably connected to the positioning block 18. The adjusting bolt 19 is threadedly connected to the adjusting block 16. When the adjusting bolt 19 rotates, the fixed cone 13 moves up and down to adjust its position.

[0037] By rotating the adjusting bolt 19, the adjusting bolt 19 drives the adjusting block 16 to move upward or downward, thereby being able to control the position of the fixed cone 13. When it moves upward, the crushing particle size becomes larger, and vice versa.

[0038] The crushing cone 12 is provided with protrusions evenly distributed on the outside of the crushing cone 12, which helps to improve the crushing efficiency. At least three groups of adjustment blocks 16 are provided, evenly distributed on the outside of the annular cone 15. The symmetrical arrangement of the adjustment blocks 16 can ensure that the annular cone 15 is evenly stressed.

[0039] See also Figure 5 The end of the driving shaft 3 is fixedly connected to a driving bevel gear 20, and the outer side of the longitudinal crushing shaft 5 is fixedly connected to a driven bevel gear 21, and the driving bevel gear 20 is meshed with the driven bevel gear 21. A positioning column 22 is fixedly connected to the bottom of the processing tank body 1, and a sliding rod 23 is slidably connected above the positioning column 22. A screen 24 is fixedly connected to the outer side of the sliding rod 23, and the screen 24 is slidably connected to the processing tank body 1. The top of the sliding rod 23 is rotatably connected to a linkage member 25, and a waist-shaped groove 26 is provided at the end of the linkage member 25. The driving bevel gear 20 is provided with a driving rod 27 facing the waist-shaped groove 26, and the driving rod 27 is slidably matched with the waist-shaped groove 26. A transmission pyramid 28 is fixedly connected to the top of the sliding rod 23, and a prismatic groove 29 that matches the transmission pyramid 28 is provided at the bottom of the longitudinal crushing shaft 5. When the driving rod 27 rotates, the transmission pyramid 28 matches the prismatic groove 29.

[0040] When the active bevel gear 20 rotates, the driving rod 27 is driven to rotate. During the rotation of the driving rod 27, the linkage member 25 is driven to move up and down through the waist-shaped groove 26. The linkage member 25 drives the sliding rod 23, the transmission pyramid 28 and the screen 24 to move up and down. When the transmission pyramid 28 moves upward to coincide with the prismatic groove 29, the sliding rod 23 rotates, and the screen 24 rotates at the same time. When the driving force intervenes, the rotation speed can be quickly increased, so that the screening efficiency can also be guaranteed. The screen 24 and the sliding rod 23 can be connected in a movable manner to facilitate the replacement of screens 24 with different apertures.

[0041] Example 2: This example discloses the following technical contents based on the previous example: Figure 6 The feed regulating unit 7 includes a right-angle drive member 30 fixedly connected to the top of the longitudinal crushing shaft 5, a feed plate 31 is rotatably connected to the top of the processing tank body 1, a feed port 32 is provided on the feed plate 31, and a spring base 33 located on the side of the feed port 32 is fixedly connected to the bottom of the feed plate 31, a regulating spring 34 is fixedly connected to the spring base 33, and a feed baffle 35 is fixedly connected to the position of the regulating spring 34 facing the feed port 32. The feed baffle 35 is N-shaped, and the feed baffle 35 can cover and open the feed port 32 when it slides and changes its position. The right-angle drive member 30 is located in the middle position of the feed baffle 35.

[0042] The motor 2 controls the feed control unit 7 by its rotation direction and speed, and when it rotates, it drives the feed baffle 35 to overcome the spring force of the control spring 34 to move. Figure 6 As shown, when the motor 2 is reversed, the feed baffle 35 moves away from the feed port 32, allowing for faster material discharge and highly crushing processing. When too much crushed material enters, the motor 2 speed can be reduced. At this time, the opening of the feed port 32 becomes smaller, and the feeding speed is reduced. However, due to the reduced speed, the torque of the motor 2 increases, the crushing force is stronger, and the crushing process can be ensured, avoiding damage to the motor 2 caused by excessive load during high-speed rotation. When the motor 2 is reversed, the feed baffle 35 can pull the control spring 34 outward, at which time the feed port 32 can be closed, and the crushing process can be carried out in a closed environment.

[0043] A first discharge port 36 and a second discharge port 37 are formed on the side of the processing tank body 1. The first discharge port 36 is flush with the bottom of the tank body, and the second discharge port 37 is higher than the first discharge port 36. When the screen 24 moves to the bottom, it is flush with the second discharge port 37. The crushed waste residue is obtained through the first discharge port 36, and the crushed residue with an unsatisfactory particle size is obtained through the second discharge port 37. Repeated feeding and crushing can be performed multiple times until the crushing is complete.

[0044] A crushing method for a nonferrous metal waste slag crushing device adopts any of the above-mentioned crushing devices for crushing.

[0045] Working Principle: During operation, non-ferrous metal waste is placed from the top of the equipment and motor 2 is turned on. Motor 2 drives drive shaft 3 to rotate, driving longitudinal crushing shaft 5 and cone crushing assembly 4 to start crushing. The longitudinal crushing shaft 5 controls the feed control unit 7 through the direction and speed of rotation to achieve feed rate adjustment.

[0046] The longitudinal crushing shaft 5 simultaneously rotates the eccentric drive column 14, causing the crushing cone 12 to cooperate with the fixed cone 13 to complete the crushing. Turning the adjustment bolt 19 drives the adjustment block 16 up and down, thereby changing the position of the fixed cone 13. The crushing particle size increases when it moves upward, and decreases when it moves downward.

[0047] When the driving bevel gear 20 rotates, the drive rod 27 drives the linkage member 25 up and down through the waist-shaped groove 26. The linkage member 25 further drives the sliding rod 23, the transmission pyramid 28, and the screen 24. When the transmission pyramid 28 moves upward to align with the prismatic groove 29, the sliding rod 23 and the screen 24 rotate synchronously, achieving efficient screening during the up and down movement. The driving force can quickly increase the rotation speed to ensure efficiency. The screen 24 and the sliding rod 23 are connected with each other to facilitate the replacement of screens 24 with different apertures.

[0048] Motor 2 controls the feed control unit 7 through its direction and speed. Rotation drives the feed baffle 35 to overcome the force of the control spring 34. When motor 2 is reversed, the feed baffle 35 moves away from the feed inlet 32, accelerating material discharge and making it suitable for high-efficiency crushing. When the feed is excessive, reducing motor 2 speed reduces the opening of the feed inlet 32. This lower speed also increases motor torque, enhancing crushing force and preventing damage to the motor due to excessive load. Reversing motor 2 also causes the feed baffle 35 to pull the control spring 34 to close the feed inlet 32, achieving closed crushing. Speed ​​control also allows for better sizing of non-ferrous metal waste slag of varying composition.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
